This undated handout released by the City of London Police shows retired TV producer David Harris. A retired television producer has been convicted on Thursday, May 18, 2017 of trying to hire hit men to kill his partner, after a jury rejected his claim that he was merely conducting research for a thriller. Prosecutors say David Harris offered three men large sums of money to kill his partner, Hazel Allinson, a former scriptwriter. Both worked on long-running British TV police series "The Bill."
